What does this mean? In a nutshell you can easily add additional gauges that the OEM did not equip on your truck with your Heavy Duty WatchDog or Heavy Duty GT.
What gauges are we talking about? Pretty much the skies the limit – Boost, Pyrometer, Water, Tranny, Rear-end, Ambient Air, etc, etc. If the gauge has a 5 volt sensor, it can be displayed digitally inside the cab. Warning levels can be set on many of these gauges to warn you when max levels, that you have set, have been exceeded so you can take action to prevent damage to your rig.
